After a prolonged series of delays and missed deadlines, Amtrak has officially set a start date for its fleet of next-generation Acela trainsets, known as Avelia Liberty trains. These new trains will run on Amtrak's high-speed service along the Northeast Corridor between Washington D.

Amtrak first introduced its Acela product in 2000. The NextGen trains were outlooked to enter service in 2022, but experienced numerous hurdles delaying their introduction.

The “NextGen Acela” is a key part of Amtrak’s plan to broadly modernize its fleet. This plan also includes the new “Amtrak Airo” trains to come to routes along the East Coast, more efficient long distance traveling and upgraded train interiors.
